Permitted Development in England: What You Need to Know

Permitted development rights let many home projects proceed without a planning application. Understand where they come from, why they vary by property, and the most common reasons they are restricted across England.

Permitted development (PD) rights come from a single piece of national legislation — the General Permitted Development Order — that applies across England. They grant planning permission in advance for defined classes of work, within set limits. But the rights attach to the property, not just the project, so two identical extensions can have different answers depending on the house and where it is.

When it may be permitted development

These are the common features that keep a project on the simpler route.

The work falls within a defined GPDO class — such as rear extensions, roof alterations, or outbuildings — and stays within that class's national limits.
The property still holds its permitted development rights: they have not been withdrawn by an Article 4 direction or removed by an earlier planning condition.
The house is not listed and not in a position (for example fronting a highway) where the relevant right is curtailed.

When planning permission is more likely

These are the usual triggers that push a scheme beyond straightforward PD rights.

The project exceeds the national size, height or volume limits for its class, or affects an elevation the rules protect.
The property is listed, in a conservation area, or covered by an Article 4 direction that has withdrawn the relevant right.
A previous permission for the property removed permitted development rights by condition — common on newer estates and conversions.

What CanUBuild checks

Faster answers before you speak to an architect or builder

The tool is designed to answer the first question most homeowners have: is this worth pursuing, and what is most likely to block it?

CanUBuild reads the designations on your exact address from national datasets — conservation areas, listed status, Article 4 directions, flood risk and tree preservation orders.

Each project workflow applies the relevant GPDO limits to the measurements you enter, so you see whether the scheme is likely to stay within permitted development.

You see decided applications near you, so the national rules are grounded in how your own local planning authority actually decides.

FAQ

Questions people ask before starting a project

Are permitted development rights the same everywhere in England?

The rights themselves are national and identical across England, but whether a given property can use them depends on its type, its designations, and its planning history — all of which vary locally.

What can remove permitted development rights?

An Article 4 direction made by the local authority, a condition attached to an earlier planning permission, or the property being listed can each remove or restrict permitted development rights.

Can I rely on permitted development without checking?

It is risky. Because the rights are conditional and property-specific, the safest approach is to confirm the designations and history on your exact address before assuming a project is permitted development.

What is a lawful development certificate?

It is a formal confirmation from the council that a project is lawful permitted development. It is optional but useful as proof — for example when selling — that the work did not need planning permission.
